Author's note: This will be my first fanfiction ever. I have been writing it for a while but never put it up for people to see until now. Just so you know I am a huge APRITELLO FAN and you guys will get to see some of that in this fanfiction. I know there will be some mistakes in it as far as spelling goes, so if you can help me out it would be great. I would love lots of reviews and ratings. And thank you for giving my story a chance.
PLEASE, PLEASE, PLEASE read and review this story. It starts out slow but gets so much better as it goes along. I'm really excited for people to finally get to read it for the first time. The stuff that happens with the Shredder and Donnie will only be the beginning because I have so many ideas and even some new characters to add in eventually. (Such as: Shadow Jones, Mona Lisa, Nari Uotain, Clover Olaith, Venus De Milo, and so many more.)
Disclaimer: I do not own TMNT (I wish I did) and my work has been inspired by many fanfic artists, so if you read something that looks too close to yours I'm sorry it was not my intention.

The Antidote

"Hey Donnie are you almost done? " Leo asked from sitting over on the desk in the far corner of Donnie's lab.

"Yeah Leo don't worry, one shot of this and Karia will have her humanity back" Donnie said excitedly, but still rather tired sounding. He was hanging his head over the table with his tongue sticking part way out as he concentrated and continued to mix various chemicals into different sized test tubes.

"And then I will finally have my lost Miwa back." Both Donnie and Leo jumped when they heard their masters lost sounding voice. He had already lost her once, and none of his sons wanted him to lose her again.

"Hai Sensei" Leonardo said as he and Donatello bowed their heads in respect.

BEEP, BEEP, BEEP, Donnie turned around to his finished product cooling off, as the centrifuge it had been placed in stopped spinning. "Yes, and with this Father, Miwa can finally come back to us...she can be on our side again" Donnie said after a short pause. "And I promise Sensei, once she is back with us, I won't rest until I turn her human again, this is only the first small step of many." With that Donatello bowed his head once again only to have his father's hand resting on his shoulder to stop him.

"My son look at me" Splinter asked with a sad smile.

Donnie looked up into his father's eyes, his hand still placed lovingly on Donatello's shoulder. "Donatello, what you have done for her is enough already, and I can not thank you enough my son. But once we get Miwa back, I wish you to take it easy and relax, for you have done enough for now. Are we clear? "

"Yes Sensei" Donnie said sporting a weak, tired smile.

"Oh my son come here" as he pulled Donatello into a much needed hug. Donnie had been working nonstop on a cure for Karia for close to a month now. Only sleeping when his body would collapse from exhaustion on his work bench while going over notes. His brothers would then sneak in and take Donnie to his room to catch up on the well deserved sleep his body craved.

"Come on Don, you need some sleep" Leo said as he took hold of Donnie's arm, and put it around his shoulders to take his tired, brainiac brother to his room so he could finally turn in for the night.
